On Spufford's Unapologetic:
A central worry for him is not that the rational justification for belief has been undone. Faith is not about that anyway: as Coleridge noted, the best argument for Christianity is that "it fits the human heart".
The Lion's World:
None of this proves the existence of God in the way a science would demand because its evidence arises from the inner lives of individuals.
It does, though, reflect a strand in the philosophical discussion of God, often forgotten today. Pascal drew attention to the problem God has in revealing himself to creatures he has made to be free, because if God were to offer irrefutable evidence then that would force a relationship of coercion, not love. God's solution, Pascal proposed, is to "appear openly to those who seek him with all their heart, and [to remain] hidden from those who shun him".
Williams' book is largely about C. S. Lewis, so the preponderance of what Daniel C. Dennett calls deepities should not be a surprise.
